PFE500SA‑28 (TDK‑Lambda) Full‑brick Package AC‑DC Power Module

This is a full‑brick package AC‑DC power module (on‑board power supply). It converts mains AC power directly into DC power. It is an industrial‑grade high‑power TDK module with 504 W power rating, conductive cooling and metal baseplate mounting. No fan is required for heat dissipation.

**Key Specifications**

- Input: 85‑265 VAC (universal global mains input)

- Output: 28 V DC, 18 A max, 504 W

- Efficiency: 89% typical

- Package: Standard full‑brick form factor, baseplate conductive cooling

- Protections: Over‑current (auto‑recovery), over‑voltage, over‑temperature protection

**Functions**

1. AC‑to‑DC conversion: Converts 220 V / 110 V AC mains into stable high‑current 28 V DC to power downstream equipment.

2. Built‑in PFC (Power Factor Correction), compliant with power‑grid harmonic standards.

3. Heat dissipation via baseplate thermal conduction with external heat sink; suitable for fan‑enclosed equipment.

4. Output voltage is adjustable within a limited range (−20% ~ +20%).

5. Comprehensive protection mechanism: over‑current, over‑voltage and over‑temperature fault self‑protection to prevent damage to downstream loads.

Applications

‑ Industrial equipment: Industrial controllers, test & measurement equipment, laser devices

‑ Telecommunication equipment: Communication base stations, switches, network devices

‑ Medical equipment (compatible with relevant safety standards)

‑ Outdoor equipment, military‑grade complete units, high‑power embedded systems

‑ High‑power power‑supply scenarios for sealed enclosures where fans cannot be installed
